A new Siena College poll shows Democratic mayoral nominee Zohran Mamdani facing an overwhelming backlash from Jewish voters in New York City, with a staggering 75 percent holding an unfavorable opinion of the Queens Democrat and just 15 percent viewing him favorably.

The numbers mark Mamdani as one of the least popular figures among Jewish New Yorkers, undermining narratives that the progressive lawmaker enjoys substantial support from the Jewish community. His unfavorable rating among Jewish voters is more than 38 points higher than his standing with the general electorate, where 37 percent view him negatively compared to 28 percent favorably. (The remainder responded they either don’t know or have no opinion.)

The steep disapproval comes as Mamdani continues to face criticism for adopting explicitly anti-Israel rhetoric during his campaign. He has repeatedly accused Israel of “apartheid,” called for a US arms embargo on the country, and championed pro-Palestinian causes. He has also accused Israel of committing a so-called “genocide” in Gaza and refused to affirm its right to exist as a Jewish state.

Many local Jewish leaders have condemned these positions as dangerously one-sided amid rising global antisemitism. Critics within the Jewish community have said Mamdani’s rhetoric ignores Israel’s right to defend itself and alienates Jewish New Yorkers who see anti-Israel animus leading to increased antisemitism in the US.

Only 20 percent of Jews stated in the new poll that they plan on voting for Mamdani, undercutting previous polling which indicated the firebrand progressive winning a plurality of New York City Jewish support. According to the poll, 44 percent and 23 percent of Jews in the city plan on voting for former New York Gov. Andrew Cuomo and conservative activist Curtis Sliwa, respectively. Only 4 percent plan on voting for incumbent Mayor Eric Adams.

Mamdani, the 33‑year‑old state assemblymember and self-proclaimed democratic socialist, defeated Cuomo and other candidates in a lopsided first‑round win in the city’s Democratic primary for mayor, notching approximately 43.5 percent of first‑choice votes compared to Cuomo’s 36.4 percent.

A little-known politician before this year’s primary campaign, Mamdani is an outspoken supporter of the boycott, divestment, and sanctions (BDS) movement, which seeks to isolate Israel from the international community as a step toward its eventual elimination. Mamdani also defended the phrase “globalize the intifada”— which references previous periods of sustained Palestinian terrorism against Jews and Israelis and has been widely interpreted as a call to expand political violence — by invoking the Warsaw Ghetto Uprising during World War II. In response, the US Holocaust Memorial Museum repudiated the mayoral candidate, calling his comments “outrageous and especially offensive to [Holocaust] survivors.”
